røykdannelse

Røykdannelse refers to the process by which smoke is produced. Smoke is a collection of airborne solid and liquid particulates and gases that are generated by the incomplete combustion of organic or inorganic materials. This process typically involves a chemical reaction between a fuel and an oxidant, usually oxygen, which produces heat, light, and various combustion products.

The composition of smoke varies greatly depending on the material being burned and the conditions of combustion, such as temperature, oxygen availability, and the presence of catalysts. Common components include carbon particles (soot), water vapor, carbon monoxide, carbon dioxide, nitrogen oxides, and various hydrocarbons. Incomplete combustion, which occurs when there isn't enough oxygen, leads to the formation of larger amounts of soot and carbon monoxide, which are particularly hazardous.

Røykdannelse is a significant factor in fires, contributing to reduced visibility and posing a severe threat through the inhalation of toxic gases and particulates. Beyond fires, smoke can also be intentionally produced for signaling, in barbecuing for flavor, or in industrial processes. The study of røykdannelse is crucial for fire safety, environmental monitoring, and understanding various chemical processes. Control measures often focus on improving combustion efficiency to minimize smoke production or on filtering and removing smoke from the air.
